BOOK-REST.

SPECIFICATION forming part of Letters Patent No. 319,105, dated June 2,1885.

Application filed July 14, 1884. (No model.)

sonville, in the county of Clarke and State of Indiana, have inventedcertain new and useful Improvements in Book-Rests; and I doherebydeclare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to that class of devices which are employed inholding` books for peo- 'ple to read; and its object is to hold a bookin variable relations to a chair, a desk, or other support, so thatitmaybe convenient to be read by a person sitting in any position or" easein the chair, or standing at the desk or other fixed support; also, tohold sketching-paper, or copy-sheets, or a memorandum in adjustablerelation to anything to be copied, whereby a person may read a book soheld and. make minutes or memoranda, or he may copy the writing ordrawing from a book or sheet held by one portion of the device upon abook or sheet held by another portion thereof.

To this end my invention consists in the construction and combination ofparts hereinafter described and claimed, reference being had to theaccompanying drawings, in which- Figure 1 is a perspective view of achair with my invention attached thereto. Fig. 2 is an upper endelevation of the book-shelf. Fig. 3 is an inverted plan view of thebookshelf, and Fig. 4 is a plan view of the memorandum-shelf hangingdown.

A represents a chair, which may be of any style.

B is a clamp adapted to be secured to the chair-bottom at one edgethereof, and having a vertical hole in which to support the body C ofthe supporting-bar, and having a setscrew, D, by means of which the barmay be secured at any desired height. The bar has a long crank-shapedbend, by means of which its top may describe a circle, turning upon itsbody as a pivot.

Eis ashelf, which serves as the book-rest. It is in the form of twoplanes meeting centrally in an obtuse angle, adapted to receive the backof an open book, while the two halves of the book rest upon the twoplanes.

Atits lower edge the shelf is provided with a ledge, F, which preventsthe book from sliding oit. The ledge has an upward-projecting lange, G,parallel with the two planes of the shelf, under which flange the loweredge of the book-cover is placed to hold the book open, while the leavesare free to be turned.

Ther shelf is held upon a metallic casting, H, in the shape of a humanhand, which is pivoted at the wrist to a socket-piece, I, by means of abinding-screw, J, which permits the wrist to oscillate vertically, andto be fastened at any 'desired angle of elevation. The piece I has asocket in its lower end, to receive and rest upon the crank end of thesupporting-bar C as a pivot, and it is provided with a set-screw, K, tosecure it thereon at any angle.

By means of the crank in the bar C the shelf may be set around to anyposition relative to a person in the chair, and by means of the pivotedwrist and pivoted socket the shelf may be set to turn the book from sideto side, or at any angle of elevation desired.

Lis a collar adjustably secured upon the rod C, by which the latter maybe supported to turn upon the clamp B when the set-screw D is loosened,or upon which the block P may turn in setting the memorandum-shelf.

M is a modification of the clamp B, adapted to be screwed permanently toa chair or bench, instead of clamping thereon removably, as clamp Bdoes.

N is the memoradumshelf, hinged upon rod O, projecting from a block, P,which is secured upon the rod C by means of a set-screw, Q.

The rod O is shaped with a horizontal offset, R, upon which the shelf Nmay rest in a horizontal position.

Then not in use, the shelf may be turned to Vhang down, as shown atFighe. This shelf may be turned around the bar C and set in any positionconvenient for the operator to use it as a writing or drawing table,while his copy may be held by the book-rest E. Thus the student, theartist, and the professional man may adapt my book-rest to serve theirper- 2. The combination of the standard with the rod O, shaped with ahorizontal offset, R, and a shelf hinged on the rod, the latter servingas a pivot to the hinge, substantially as shown and described.

In testimony whereof I affix my signature `in presence of two Witnesses.
